I started to get interested in working hot steel over 30years ago when I saw my first Damascus steel blade, but I've never actually got round to trying to make it until recently. I've been playing with old band saw blades at work the first pic is my first attempt a mix of narrow blades off the wood saw and wider off the steel saw. Lots of delaminations but over all not bad for my first attempt. The second attempt went straight in the bin for what ever reason it just didn't weld. The paper knife is my 3rd attempt its just narrow blades. Over all its a good solid chunk of steel but there is virtually no pattern to be seen without a magnifying glass. My fourth attempt is wide blades and two pieces of steel off a circular steel saw blade that was a big chunk of steel that has issues, but I haven't had time to grind it yet. I think my biggest problem is our forge at work is designed to get hot, but not get hot enough to burn steel and I don't think I'm getting the heat in to it.
